But seriously, though do you just have like a separate written story on these guys, or your bad future pictures,(I'm new to your page so if you have answered this before im sorry) , because I really want to read what happened in these situations as a whole if there is one

Sadly no there are no written stories from me about them. And they don't appear in the dark future story because the plot takes place right after Twilight became a princess in the show, it would have to take place a few years in the future for the kids to be in it. The only thing I have so far is scattered illustrations with small descriptions of moments in their lives and there's more in their reference sheets, other than that I'm afraid I have nothing. And there's a few more in my tumblr page, like this one hazurasinner.tumblr.com/post/1… that shows how the mane six managed to have children.

2. That being said... I suppose one minor detailing to mention is Apple Syrup's freckles. Since you are using a lighter shade of orange for Apple Syrup's fur-coat, white freckles can be harder to define artistically. A refinement suggestion(s) can be that you may want to sharpen her freckles by adding ultra-thin black outlines on the freckles, or enlargen her freckles to be more noticeable.

3. As a creative suggestion, if you find yourself doing another like this, you could have a scene where Apple Syrup's head is all but covered over by Applejack's stetson, with only a goofy grin from the little filly showing from underneath. Meanwhile, both Element parents look upon their daughter with joyful amusement.

Apple Syrup is Applejack and Rarity's daughter, and yes there's magic involved. I actually have the explanation in a small comic I made because many people have asked the same, you can see it here hazurasinner.tumblr.com/post/1… hope it can clear the question.
